-1 Clair'm, (Cl. 74-107) m The present invention relates to an improved binding machine and more particularly to an improved machine which binds together a stack of aligned sheets by forming a row of binding holes. through the sheets and attaching a binding member having 'abackbone' with curled, resilient fingers which "areinserted through the holes.

The invention relates, in one form, to a binding mechanism having a frame with a punchingstation thereon and a binding station thereon co'operatively related to completely bind a stack of aligned sheets with a binding member. A complete operation requires both punching and attaching of a binder. Punching is. performed at the punching station, andbinderlattachment at the binding station. The punching station is provided with a supporting platform and a plurality of longitudinally aligned,

spaced punch memberslcoacting-withadie member, with the punchmembersactuated bya ,driving means including a toggle linkage and ani operatingcarn. The binding station is provided with a comb member having a plurality of teeth projecting above a supporting platform and spaced toenter the spaces between the curled fingers attached to the backbone of a binding member. A plurality of hook members are positioned adjacent'the teeth and the teeth m'ove longitudinally forcing the heck members over the fingers of the-binding member. The hook members then move laterally to draw open the, curled fingers. Longitudinal movement of the teeth and lateral move- 'ment of the fingers are caused by driving means operated by anoperating cami' The entire mechanism is driven by an operating sh'aft carrying a punching cam operating the punch mechanism-and'positioningfand holding the punching mechanism in apaper receiving position during a binding portion of rotation of the operating shaft. The operating shaft also carries a binding cam which operates the binding members and'positions and holds the binding mechanism in a binderrec'eiving position during a punching portion of rotation of the operating shaft.

As showninthe drawings: a r The bindingmachine embodying theprinciples of the present invention-is illustrated with certain details o f both a punching station 20 and a binding -station22 in An object of the invention is to provide an improved 'portablemachine whichfis used for a complete binding operation.

Another object ofth e invention is to provide an im proved binding machine which performs a complete operation including punchingaligned openings in stacked sheets and applying a binding member having a backbone with fleirible, curled fingers which enter'the'openings in thesheets. 3 Y t A further object 'of the invention ,is to provide an improved punching 'and binding machine which is I and hold either thepunchingfior binding members in Figures 1 through 5, -withFigures .6 and 7'illu strating certain details of thepunchirig station.- The mechanism is provided with;a frame 10 having a baseplatelZ. Rising from the base plate. are supporting pedestal members 14 and 16 whichcarry certain operating elements of the machine. A rear shroud 18 forms a protective enclosing for the back portion. of the machine. At its front end, the machine has the punching station 20, and

located at the upper portion of the machine is the binding station 22. a

The machine operates to bind together a stack of individual sheets 24, Figures 2 and 2a, to form a booklet 26, or the like. A series of elongated holes 28 are punched along one edge of the stack'of sheets 24 for attaching a binder 30. The binder has a backbone 32 to .which is attached, at spaced intervals, a plurality of curled resilient fingers, such as 34, 36 and 38; The fingers are attached or integral to project from one edge 40 of the backbone and curl in a generally annular form with a free endAZ curled down along the inner surface of the backbone, 32. The sheets are thus held together by the binding member 30, and can be turned freely with their openings sliding over the curled fingers 34, 36 and 38. V

In operation of the machine, the aligned row 'of holes 28 is punchedin the sheets, and the binding member 30 is applied by opening the curled fingers 34,36 and 38, and sliding the ends 42 through the openings. The curled fingers are then released and resiliently returned to machine.

theircurled position to complete the binding of the stack of arrn.44. The operatingarm 44 has a general u-shape and extends. as a yokewith side arms Y46 and 48, Figure 1, eXte'nding .-at,each side of-thefmachine and connected by a bar 5.0, extending across the ends of [the arms and providiiig, a handily gr spable bar for swinging the side arms 41/6 and 48' through their operating are for operating'the The sidearmsi46 and 48 are secured 'attheir lower ends tdcoiinecting hubs52 and 54-which have openings through the center-,jfandhaveikey. slots ,to receive lockinglkeys 5615a'i1d'58, which, are shown in Figure 'The keys 56 and 58 are locked" in keyways in operatingshafts 60 and 62.; Thus, when the operating handle 44is swung through anQQfGQIthe operating fshaft-s .60 and 62will be rotated.

"""The'handle or arm 44, in operation, swings through van are from the punching position shown at P in Figure 4 to the binding position shown at Bfin Figure 4. At an intermediate position shown at I, neither the punching stahon-20, nor the binding station 22 is in operation. A Thus, when the handle and operatingshafts swing through the binding are from I to B, the punching mechanism is fixedly heldin a position to receive sheets'of paper, and the binding individual pins 98. i I are withdrawn, the punch-operating bar 100 will descend,

individual operating pin 98, is h i A v V of the punch, and which carried in a punchoperat1ng bar 100. If desired, individual punches 82 may be temporarily or permanently taken out of operation by Withdraw- When the individual pins 98 and the upper end of the'p'unch 82 will be received by the individual punch 82 will I be forced downwardly to punch a hole in the stack of sheets when the operating bar 10t),-is pushed downwardly: 1

The operating bar is supported at its ends in bearing blocks which. are guided in-vertical movement to hold the bar in alignment as it moves up "and down. It will be understood that the guiding mechanism and the operating mechanism for each end of the punch operating ing mechanism is attaching the binding member 30.

While the handle is swung'fromthe intermediate position the binding mechanism is positioned and fixedly held to receive the binding member and the punching-mechanism. is operated. When a stack of sheets bound by the machine, it is first placed on a first platform area 64 at the punching station, Figures 1 and 4, and then raised to a second platform.- 66-at'the binding station 22. The second platform is vertically oifset from the first platform 64, and raised slightly for convenience of handlingthe sheets.

The binding station 20 includes a die plate 68 which is set'into the surface of the'base 20, so as to be substantially flush with the top. As. illustrated in Figures 3, 4 and 7, the stack of'sheets will be slid into place over the die plate 68 until its edge reaches the stop' face 70 of a spacer bar 72. The spacer b'ar rests on the die plate 68,

and carries on it a die stripper plate '74. The stripper platecurves upwardly at its forward end 76 to. define a throat*"78into'which the stack of sheets is. convenient- 'ly-fed against the stop face 70.

' "As illustrated in Figure-6, the die plate 68 has a series of 'die openings 80 which are entered by punches '82. The base 12 has an'elongated slotted opening 84 cut therein inorder that the punched slugs of paper which are cut from thestack of sheets may drop downwardly.

The punches are mounted in unit sub-assemblies with each" sub-assembly being suitably mounted on the frame of the "machine. The separation between the subassemblies is shown at 86 in Figure 6. When aligned in a row; the sub-assemblies form a complete longitudi-= i 'nally' aligned series-of punches 82, which are separated and spacedfrom each other, to correspondwith the die openings 80 and form the longitudinally aligned rowof openings -in thestackof sheets The. punches 82 Work in .ofithepunches .and bottoming on the uppfir sur face of Qt t ipPcnn t 4- h chmf the:punches,v ;82;is; pushed idownwardlyuzbyu an unison and arernormally held'in their uppe'rmostpo'ised position by coil compression springs 88 surrounding each one end need be described'inidetail.

1 As shown at the right end of the machine inFigu res 5 and ,6, secured to the 'end of thebar' is'avertically sliding bearing block 108'. The; block has a re'cessf110 to project above and below thebar for firmly transmitting verticalmotion thereto, and a bolt 112, extendsthroug'h the side'ofthe block 108 and threads .into the end of the bar 100. The vertical slidingfbloclg 108 has vertical grooves 114 and 11 6 out into its side into which project ridges 1181andf of supp'orting frame members 122 and 124'. The fr'ameflmember's' are held together by bolts, such as shown at 126,1 and arerigidly mounted to extend upright from the base12f The frame member 124 hasa laterally opening slot 128 to accommodate. reciprocating movement of a driving link 130, as willbe described. i

The bearing block 1081which carries'the. punch operating bar 100,,is moved and l,down,by-toggle links 132 andgl34. The lower toggle link 132v is pivotally connected to the bearing; block by a pin-136. 'I heupper toggle link 134 is pivotallyfconnectedfto a .fixedlpin 1 38 which is mounted on theframe piece..124. The toggle links 132. and .134 arev joined to' each other by a pin' 140 hiGh. also connects them to the drivinglink- 130,

which has a bifurcated end, so lasto provide aslot 142.

, T pu r vi l nk-1 0,, f r he-r a said f he machine, as illustrated particularly in Figures 3, 4 and 5 is, horizontally reciprocatedby a follower 144 riding in a closed positive operation tcam slot 146 in .a punchoperating-eam .148. The punch-operating cam 148, is

V keyed to rotate withthe operating shaft I The. follower 1-44iis illustrated as being in the form 'of a roller '150; carriedon a pin1522which extends across a slot 154formed in the bifurcated end of'the, dn'vinglink The cam slot 146 is shaped to have an operating 7 p'or-tion l56; Figures 3 and 4," and aholding'portion "158, The holding portion '1'58'extends substantia y to i F the point 160,- and is at a-constant-radius from the center which engages the upper end i of the follower 144 will occur when it is in that portion of the cam track. However, when the follower 144 is in the portion 156 of the cam track, it will be reciprocated laterally. The follower will be in the holding portion 158 during the time that the operating handle 44 is swung through the binding portion of its arc, which is from the position I to the position B, and will be in the operating portion 156 while the handle is swung from position I to position P.

The driving link 130 is guided in a bearing block 162, which is mounted on a frame member 164, Figure 5, the-frame member being secured to the base 12 of the. frame by bolts 166. The frame member 164 also has a journal 168 which supports a bearing 170 that is integral with the hub 54 of the handle, so as to provide additional support for the operating shaft 62.

The binding station 22 is provided with an opening 172 in the platform 66 on which the stack of sheets rests while the fingers, such as '32, 34 and 3-6 are being inserted into the slots in the sheets. In the opening 172 is a flush plate 174 which provides a gap 176 along one edge. Through this gap project teeth 178 of a comb member 180. The comb member 180 is suitably mounted beneath the platform 66, and the teeth 178 project upwardly therefrom, Figure 1.

The teeth 178 are spaced so as to enter the spaces between the fingers of the binding member 30 and engage the inner surface of the backbone 32. The backbone will thus be held while the fingers are being uncurled by hooks 182.

The hooks 182 project upwardlyabove the surface of the platform 66, and move through slots 185 which extend laterally from the comb teeth 178, and which are formed in the insert 174.

As may be viewed in Figures 1, 3 and 4, the hooks 182 have longitudinally extending hook ends 184 which before spreading, as shown in Figure 4, lie up against the fingers 178. The binding member 30 will be dropped over the teeth 178 of the comb member 180 and the ,comb member shifted longitudinally, so that the ends 184 of the hooks 182 willpass over the curled fingers of the binding member. The hooks 182 will then be drawn laterally from the position shown in Figure 4 to the position shown in Figures 1 and 3 to open the curled fingers.

The comb 180 is mounted on a carriage member 186 which is shiftable in a longitudinal direction. For shifting the comb, cam followers 188 and 190, Figures 3, 4 and 5, project below the carriage and are operated by cam plates 192 and 194. The cam plates are supported on a pivotally mounted shaft 196, which is carried at its ends in the pedestals 14 and 16. The cams ure 3, the cam 1-92 willfirst' push the carriage 186 and its comb 180 to theleft, as shown in Figure 1. Continued pivotal movement of the shaft 196 will push the hooksupporting bar 198 to the left from the position of Figure 4 to the position of Figure 3, thereby opening the resilient fingers 32, 34 and 36. When the stack of sheets has been placed over the fingers with the ends of the fingers passing through the holes in the sheets, the shaft 196 is rotated back, whereby the fingers will be released to curl back to their normal position, and the comb teeth 178' will then be positively shifted to the right, Figure 1, by actionofithe cam 194 and the follower 190. i i

Pivotal movement of the binding drive shaft 196 is obtained by a crank 212 at the end of the shaft.v

192 and 194 are arranged relative to the followers 188 and 190 so that the comb 180 is positively moved to the left, as shown in Figure 1, by the cam 192 acting on the follower 188, as shown in Figure 5. This movement will carry the binding member 30 to the left so that the hook ends 184 enter the curled fingers.

The comb 180 is positively moved in the opposite direction by the cam 194 acting on the fdllower 190 to shift the comb to the right away from the finger ends 184.

The resilient fingers 34, 36 and 38 are drawn to the spread or open position by sliding a hook supporting bar 198 to the left, as shown in Figures 3 and 4. The hooks 182 are each secured to the bar 198 which is slid-ably mounted on. guide rods 200, 200. Bosses 202 extend downwardly from the ends of the hook supporting bar 198 g to be connected to hook-operating links 204 and 206, Figure 5. The hook-operating links are pivotally connected at their ends by pins 208 and 210 to the face of the cams 192 and 194. Thus, pivotal movement of the shaft 196 will operate both the comb and the hooks. As the shaft 196, Figures 3 and 4, moves in a counter-clockwise direction from the position of Figure 4 to the position of Figradius from the center of the operating shaft 62, and an operating portion 222 which is of varying radius from the center of the shaft 62.

. While theoperating handle 44 is being swung through the are from position I to position B, which is the binding portion of the arc, the follower 214 is in the operating portion 222 of the cam. This forces the cam follower 214 from the position shown in Figure 4 to the position shown in Figure '3, and back. While the operating handle44 is swung through the arc from position I to position P, the follower 214 is in the portion 220 of the cam track, and the binding elements are held in fixed positions for receiving a binding member 30.

As illustrated in Figure 5, the crank arm 212 is secured to the end of the shaft 196, and the follower 214 altthe end of the crank is in the form of a roller 224, journaled on a follower pin 226 mounted at the opposite end, also carrying a follower 230, operated by a cam 232, and the earn 232 operates in a manner identical to the cam 218 and, therefore, the pants need not be described in detail.

In operation of the mechanism, the operator begins with the handle 44 in the position shown at I, and places a stack of sheets to be bound in the throat 78 against the stop surface 70. The handle 44 is then brought down to position P, whereupon the operating shaft 62 is pivoted'to pivot the punch-operating cam 148 from the position of Figure 3 to the position of Figure 4. This straightens the toggle links 132 and 134, and the operating bar 100, Figure 7, drives the punches 82 downwardly into the die openings 80. When the handle 44 is brought back to the position I, the punches 82 are released by the operating bar moving upwardly. The punches are positively lifted in a positive stripping action through links such as 234 and 236, which are connected between the operating bar 100 and the ends of the punch lifting bars 90. The stack of punched papers is then lifted from the lower platform 64 to the upper platform 66. During the time the papers are being punched, the comb and the hooks 182 are held in position to receive the binding member 30 which may be placed on the machines by an operator or by an assistant, since this may be done simultaneously with punching the sheets. The binding member 30 is dropped over the teeth '178 of the comb member 180. The punched sheets are transferred from the punching platform 64 to the binding platform 66. The handle 44 is then swung through the binding are from the position I of Figure 4 to the position B. By operation of the binding cam 18, the binding shaft 196 is pivoted in a counterclockwise direction from the position of Figure 4 to Figure 3, to first move the teeth 178 to the right, as shown in Figure l, and then to draw the hooks 182 which have engaged the resilient fingers of the binding member from the position of Figure 4 to the position of Figures 1 and 3. The individual fingers 34, 36 and 38 are then inserted into the holes in the stack of sheets and the operating handle 44 is brought back from the position B to the position I. This returns the hooks 182 to the position of Figure 4,
